    ZFS - Mixing 4K/512 Drives...

    Thanks guys. I do remember I have a SAS internal to external bracket left over from my hardware (desktop) days. I'll probably end up going that route and building a new pool in an old external SAS box (... have to find drive tray keys!) and migrating then moving the disks back into the...

    Hmm. Sigh, can anyone recommend a cheap HBA with external ports?

    Thank you sir. I'm okay with the performance hit

    ZFS - Mixing 4K/512 Drives...

    I just want some confirmation that this is not a big deal. I understand I'll see a performance penalty since the pool doesn't have the correct ashift, but other than that is there any big issues? I'm just hesitant since I'm going to spend close to 2K on replacing 11 drives. Ideally I'd rather...

    Has anyone ever heard NTFS doesn't need defrag?

    I think "need" is relative. Without looking at the fragmentation level of any particular file system, the need to defrag can be questionable. Without understanding how a working dataset is used, even fragmented, you can't really say what is "needed". What if we're talking about a 4GB dataset...

    "TRIM" Over CIFS/NFS/iSCSI?

    VMDKs don't shrink automatically. Your confusion is between a thin-provisioned filesystem (block device) on ZFS and how VMDKs work.

    Windows reFS vs ZFS

    The only advantage you'll get is familiarity with Windows. What's wrong with vmware tools on OI? Are you accessing OI via the Console?

    best way to setup six 2tb drives in zfs?

    mirrored raidz? So you're introducing hardware raid? Go 2x3-way mirror if you're concerned about failure. Cuts your available space down a bit, but meh that's always going to be the trade-off in any type of "RAID" system. Keep a hot spare if you can, if not keep some cold spares around.

    Question for those running Sabnzbd & ZFS/OI

    This. If I was going to run all my apps on one OS I might as well not virtualize. I mean I could also run Sickbeard and Sabnzbd together too, but I decided against it. Makes it cleaner and easier to use and if I need to, I can move the VM to another server. ... Now all I need is vCenter :D

    Question for those running Sabnzbd & ZFS/OI

    I'm running ESXi All-in-One with OI as a VM+various VMs performing different tasks. One of them is a Windows VM that runs Sabnzbd. It downloads to a CIFS share on OI, specifically for holding temporary downloads so something else can organize it. I have mapped network drives, but for Sab, I...

    Cheap LSI SAS2008-Based HBA with External Ports?

    I tried searching, but does anyone know of a cheap LSI SAS2008-based HBA? It doesn't matter if its an OEM that I have re-flash (ala IBM M1015). Of course I can use adapters, but I'd rather not take up the space in my chassis. Thanks for any help (PS I'm looking at the LSI 9200-8E right...

    ZFS can you have multiple vdevs for a ZIL

    Cool, leave it up to Nex7 I was also questioning what the potential benefit would be having multiple mirrored vdevs as the point is data has to be committed, so it would be as slow as the slowest vdev and in turn the vdev would be as slow as the slowest disk As Nex said, the only way it...

    ZFS can you have multiple vdevs for a ZIL

    I don't have a zil since a have no space to put it, but there's a question that popped into my head this morning that I can't seem to find an answer on. Some Oracle blogs suggest its possible but I don't know if they are doing it on the hardware level. I would try this in a VM but I'm at work...

    ZFS and SAS expanders with SATA drives a toxic combo?

    :D No prob, it was a long shot, I just had to ask. Yeah, I'm trying to hold off as long as I can and see if someone will put out some 3TB SAS. I might just add 3-way mirrors to my existing zpool (currently using raidz2). That will take some of the sting out when I add a vdev.

    ZFS and SAS expanders with SATA drives a toxic combo?

    He's trumpeting a solution that works to a problem he's seen. Geez. You can rail all you want against what you see as the problem, but if we don't have your solution in hand, you think its a smart idea for companies or anyone that wants a production-level set up to risk using a setup that...

    Deleted Folder in Root of ZFS Share-Need to Restore

    No. It's a kernel-level service. You can run Samba, but in the past, I've heard it has very iffy performance on OS. I've never looked into on OI, the built-in stuff works for my purposes (ACLs/Previous versions is all I really care about when it comes to CIFS)

    Deleted Folder in Root of ZFS Share-Need to Restore

    This wouldn't be possible via the kernel-level CIFS service implemented in OI, no? I guess it depends how he implemented CIFS sharing.

    Deleted Folder in Root of ZFS Share-Need to Restore

    Cool, its a little daunting at first. I think Oracle still has the zfs administration docs available, so it might be helpful to read that. That's how I learned, and OpenSolaris was my real first *nix-based system too. Quick and dirty, ZFS. ZFS "starts" with zpools zpools are made up for...

    Deleted Folder in Root of ZFS Share-Need to Restore

    By the way, you can't change the mapping of your storage zpool zfs' filesystems to the actual folders (maybe mountpoints but it defeats the purpose of the kind of management I'm suggesting). My (our) suggestions is to create segregated filesystems with auto-snapshots. This helps with space...

    Deleted Folder in Root of ZFS Share-Need to Restore

    This. I would also recommend using different filesystems (eg zfs create pool/MYIMPORTANTRIPS :D) for any data that has obvious delineation. And then set up automatic snapshots for that file system. Of course, that also means this would be a separate CIFS Share (or NFS Mount). Sucks...

    OpenSolaris derived ZFS NAS/ SAN (OmniOS, OpenIndiana, Solaris and napp-it)

    I don't know why I can't find this, but if I already have an existing OI server serving out CIFS in Domain mode, iSCSI (with Auth), Time-Slider, etc do I need to do anything special to install Napp-It? Should I at least disable Time-Slider (redundant?) or will Napp-it do it for me?

    Reliable high IOPS SSD that dpesn't need trim to perform?

    I'm sorry, but I don't get why Garbage collection is a big deal for an L2arc. Once its warmed the majority of the IO is going to be read. If its not already in the l2arc (or the arc) wouldn't zfs just call it up from the zpool's vdevs. I'm pretty positive when a miss occurs on the arc and...

    Connecting a ZFS system to a Windows workstation -plus a question about error correct

    Oh I know its technically possible, its just not really feasible/justified for myself.. .at least right now. I find myself spending a lot of time on my laptop lately and not my workstation. I have work/play offloaded to VMs on my All-in-One. I could justify another CPU or another server...

    Connecting a ZFS system to a Windows workstation -plus a question about error correct

    Hmm Seems like a job for FC lol. Can you put Steam games to a network drive? I think you're pushing your luck, I wouldn't expect great performance out of GigE. iSCSI seems more of your use-case, but that's your call. I dream of a day that I will one day be able to do 10GbE and iSCSI (or...

    Does SATA 6GB/S require special cables?

    Improving low small read/writes on OpenIndiana iSCSI

    Is destroying the zpool and rebuilding (zfs send it out and receive it back in if that's at all possible) a viable option? If not seems like ZIL+L2ARC would be the only reasonable "tweak". Should fix some of your random IO issues.. I guess it really depends on your IO profile (read or write...

    IPMI has been a very very useful tool, even in a home environment. For enterprise/data center... its a necessity (ok ok, IP KVM, whatever). Maybe I'm just lazy, but, for example, last week I did my ESXi 5.0 upgrade without having to drag my ass across the house where my server is and sit in...
